我在我的项目中使用Spring Integration框架。数据库是在AS400上运行的db2。我必须一个接一个地调用两个存储过程。我的第一个存储过程执行没有任何问题，并将消息传递给第二个stored-proc-outbound-gateway。在这里，奇怪的事情正在发生。看来第二个存储过程成功执行，但奇怪的是第二个存储过程出站网关没有产生任何回复消息。
以下是连接到SQL Server后的日志语句：
[org.springframework.jdbc.core.JdbcTemplate.doInCallableStatement] CallableStatement.execute() returned 'true'
[org.springframework.jdbc.core.JdbcTemplate.doInCallableStatement] CallableStatement.getUpdateCount() returned -1
[org.springframework.jdbc.core.JdbcTemplate.extractReturnedResults] CallableStatement.getUpdateCount() returned 1
[org.springframework.jdbc.core.JdbcTemplate.extractReturnedResults] CallableStatement.getUpdateCount() returned -1
当我连接到db2时，相同的语句是不同的：
DEBUG [org.springframework.jdbc.core.JdbcTemplate.doInCallableStatement] CallableStatement.execute() returned 'false'
DEBUG [org.springframework.jdbc.core.JdbcTemplate.doInCallableStatement] CallableStatement.getUpdateCount() returned 0
DEBUG [org.springframework.jdbc.core.JdbcTemplate.extractReturnedResults] CallableStatement.getUpdateCount() returned -1
任何人都可以说这里有什么问题吗？ 如果您需要任何其他信息，请随时问我。

这意味着存储过程没有产生结果。
答案 1 :(得分：0)
我遇到了同样的问题，并且我将其修复，该异常意味着转换步骤返回null（不应为null），因为我创建的消息无法正确转换。尝试调试到转换步骤，然后看看结果如何。例外发生在我的第二行：
IntegrationFlows.from(testChannel() )
.transform( new ObjectTransformer() )
.<Object, Class<?>>route(Object::getClass,
